PETER MOCABE, OF NEW YORK,

SPEGIFIGATIONformi'ng part of Letters Patent No. 728,277, dated May 19, 1908. I Application filed January 8, 1903. Serial No. 138,198. (No model.) I

TO all whom it may concern:

-Be it known that I, PETER MOOABE, a citizen of the United States, an'd a resident of the borough of Manhattan, city, county, and State of New York, have invented'a' new and useful Improvement'in AttachmentsfonWindowe- Sash, Sliding Doors, or the Like, of which the following is a specification,Qreference being had to the accompanying drawingsfin which- Figure 1 illustrates the'inveution as applied to a window-sash. The view is shown irrelevation, except thatone of the attachments is shown in vertical section through the break-. ing away of the window-sash. Fig. 2 illustrates an enlarged view of the attachment as applied to a window-sash, taken in vertical section. Fig. 3 illustrates an elevation or face View of the edge of a window-sash, showing the invention in elevation. Fig. 4 illustrates a detail of the brake device.

The object of my invention is to provide means whereby the side movements of window-sash will be avoided,-s0 that the sashlocks may properly engage with each other,

and by the same means 'all noise resulting from rattling'of thesashwithin its frame is prevented, the raising and loweringof the sash is made smoother and better in action, and also sash-cords are done away with.

Referring more particularly to Fig. 2, A is v a casing, preferably made of cast metal, having two sockets B B. Cis' a plate adapted to enter the open mouth of the casing A. It is slotted in'its central part,as at D, and is pro.

vided with two lugs E E, which may advantageously be cast integral with it, through which passes the axis F, upon which a wheel H Hare lugs which.

orroller G revolves. may likewise ;-be cast integral with the faceplate O, upon which are properly supported springs I I, which rest at their inner ends in sockets B B. K K are two face-plates fastened by screws'L tothewoodwork to which the device is attached.- These platesK K overlap the. face-plate G, the ends of which are recessed, asat MM, to receive the thick- The s'p'ringsI I .aregraduated in strength and-stifiness, depending upon the weight and character of the sash or door with which the device is used.

Onemethod of applying the device is shown tratesone of theside. bars ofajwindow-sash. X'jisthe frame thereof. A suitable recess is in ,the drawings and. is] asfollowsz X'illuscase A and provided with recesses in the bottom of the main recess for the reception ofthe sockets B. I The box or casingA is placed within the recess in the-side of the'sash and held -fi-r'mly therein not only byits sides and themejecting sockets B, i-nconjunction with which Isometimes-use projecting lugs O O, castinf tegral with the casting, but also by screws N N,

whereby the casingis rigidly held in place frame or casing there willbe no likelihood that thesprings I, which are quite stiff, shall force 7 the plates Koif from the sash-b'arI- When the. fsash'is inserted within the casing, suitable pressure is preferably'exerted, so;-that the springs are compressed" considerably,' as shown int-Fig.2, whereby,;owing to the fact that therea're preferably-atleastthree, if not four, of my devices used on each sash, (two or more on one side and two or more'on the other, as shown in Fig. 1,) the sash is held under the action of'the springs in a positionof substantial equilibrium separated from the window-casing by the degree to which the proved device, is takenout from the window rollers project beyond the side of the sash,

and owing to-this rigid or tense suspension or holding of the sash and the pressure of the-rollers against the rabbets in the casing within which the sash moves there is no possibility of any rattling of the sash by-reason of gusts of wind, the closing or opening of doors, jars in the building or in the street.

Also because the sash is relieved of ,all frictional contact between its edges and-the window-casing the raising and lowering of the sash is more smooth, even, and regular in action than heretofore.

In order that my improved device may act also as a means to lock the sash in any desired position vertically, th us doing away with sashcords, I provide a brake device whereby one or more of the rollers or wheels may be looked, as may be necessary to sustain the sash at any desired elevation. Such device may be made in a variety of ways. I illustrate one as follows: P illustrates an elastic or spring strap, preferably of metal, which is fastened at Q to the face-plate C. It is preferably given a curved outline to coincide with that of the roller or wheel. R is a little thumbnut mounted 011 the end of a shaft S, upon which is an eccentric T, and these parts are so arranged that when thumb-nut and shaft are revolved the cam will be brought in contact with the free end of the brake-strap, overcoming its elasticity and forcing it against the near arc of the wheel or roller G, thus locking the wheel. The littlethumb-nut will be located upon the inner face of the side bars of the sash-frame, easily accessible from the inside of the room. to operate one or more of these brake devices, depending upon the weight of the sash.

This device when applied to window-sash,

'as above stated, is peculiarly satisfactory in fine residences, where the noise of rattling windows is especially objectionable. It may also be beneficially used in hospitals, asylums, or shops where the machinery engenders continual pulsations, resulting in great rattling of the windows.

My invention is applicable to other uses in the construction of buildings aside from window-sash, as will be obvious to those who are familiar with such matters. I prefer to make the rollers with a fiat face having rounded or smooth edges and of brass, aluminium, or equivalent non-rusting metal. They may, however, in many cases be made of wood, celluloid, or rubber, and they may have a rubher or similar noiseless and elastic face, if desired.

It is obvious that in the event of fracture of any of the parts of the apparatus repair is exceedingly easy by simply unscrewing the confining-screws which hold the several parts inplace.

It will be obvious to those who are familiar with this art that many modifications may be made in the details of construction of the device without departing from the essentials of my invention. Among such modifications are the following: The plates K K are not essential. Other means for confining the faceplate may be employed. The face-plate may It maybe necessary be left without special confinement against lateral movement,because the pressure of the rollers or springs will hold it in place when in operation. Also the sockets B 13 need not be employed. I prefer to use them, so that the springs may have the desired length; but if the main casing A is made deep enough the springs will have the requisite length. In many cases a shorter spring will suffice. Also it is possible to employ the invention, but not in my judgment so advantageously, if it be attached to the window frame or casing, so that the rollers engage with the sash-frame, instead of being attached to the sash-frame, the rollers engaging with the window-casing. Also other means than the specific brake device shown and described to prevent or retard the rotation of the rollers may be employed. Indeed,there are many modifications which may he made in the details and still the essence of the invention be present. I therefore do not limit myself to such details. Having described my invention, I claim- 1. The combination of a casing adapted to be attached toasash orlikestructure,aspringsupported roller carried by the casing and adapted to elastically sustain the sash and a brake device adapted to be engaged with and disengaged from the roller in whatever position the sash may be and means for operating the brake.

2. The combination of an exterior casing, a plate adapted to be received Wlllllll the easing, springs interposed between the casing and the plate, a pivoted roller carried by the plate and projecting laterally therefrom and means adapted to be engaged with and disengaged from the roller to regulate or prevent its rotation and means to operate the same.

3. The combination of an exterior casing, a plate adapted to be received within the easing, springs interposed between the casing and the plate, a pivoted roller carried by the plate and projecting laterally therefrom, an elastic strap-brake fastened at one end to the said plate and passing around an arc of the said roller, a shaft accessible from the exterior of the sash and provided with means whereby its rotation will force the strap-brake against the periphery of the roller for the purpose set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

PETER MCCABE.
